私は obj-c の初心者で、いくつかのプロジェクトで asihttp を使用しています。asihttp で投稿リクエストを行う場合、この方法で行われます。
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setPostValue:height forKey:@"user[height]"];
[request setPostValue:weight forKey:@"user[weight]"];
[request setDelegate:self];
[request startAsynchronous];
コード例を使用したAFNetworkingでこれを行うにはどうすればよいですか?
AFNetworking で get Json getrequest が動作するようになりましたが、この投稿リクエストで問題が発生しています。事前に助けてくれてありがとう。
最初に追加する価値があります（この回答は、最初に書いた後6年経ってもまだ人気があるためです...）、最初に検討する必要があるのは、AFNetworkingを使用する必要があるかどうかです。NSURLSessionはiOS7で追加されたため、多くの場合、AFNetworkingを使用する必要はありません。サードパーティのライブラリが1つ少ないことは、常に良いことです。
AFNetworking 3.0の場合：
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
NSDictionary *params = @{@"user[height]": height,
@"user[weight]": weight};
[manager POST:@"https://example.com/myobject" parameters:params progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSLog(@"JSON: %@", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(@"Error: %@", error);
}];
AFNetworking 2.0の場合（および新しいNSDictionary構文を使用する場合）：
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *params = @{@"user[height]": height,
@"user[weight]": weight};
[manager POST:@"https://example.com/myobject" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error: %@", error);
}];
AFNetworking 1.0の使用に行き詰まっている場合は、次のようにする必要があります。
NSURL *url = [NSURL URLWithString:@"https://example.com/"];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
height, @"user[height]",
weight, @"user[weight]",
nil];
[httpClient postPath:@"/myobject" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString *responseStr = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSLog(@"Request Successful, response '%@'", responseStr);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"[HTTPClient Error]: %@", error.localizedDescription);
}];
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
height, @"user[height]",
weight, @"user[weight]",
nil];
AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:
[NSURL URLWithString:@"http://localhost:8080/"]];
[client postPath:@"/mypage.php" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString *text = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSLog(@"Response: %@", text);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"%@", [error localizedDescription]);
}];
これは、私が使用している単純な AFNetworking POST です。AFNetworking のドキュメント、wkiki、ref などを読んだ後に起動して実行するために、http://nsscreencast.com/episodes/6-afnetworking をたどり、github の関連するコード サンプルを理解することで、多くのことを学びました。
// Add this to the class you're working with - (id)init {}
_netInst = [MyApiClient sharedAFNetworkInstance];
// build the dictionary that AFNetworkng converts to a json object on the next line
// params = {"user":{"email":emailAddress,"password":password}};
NSDictionary *parameters =[NSDictionary dictionaryWithObjectsAndKeys:
userName, @"email", password, @"password", nil];
NSDictionary *params =[NSDictionary dictionaryWithObjectsAndKeys:
parameters, @"user", nil];
[_netInst postPath: @"users/login.json" parameters:params
success:^(AFHTTPRequestOperation *operation, id jsonResponse) {
NSLog (@"SUCCESS");
// jsonResponse = {"user":{"accessId":1234,"securityKey":"abc123"}};
_accessId = [jsonResponse valueForKeyPath:@"user.accessid"];
_securityKey = [jsonResponse valueForKeyPath:@"user.securitykey"];
return SUCCESS;
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"FAILED");
// handle failure
return error;
}
];
AFHTTPClient * Client = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:@"http://urlname"]];
NSDictionary * parameters = [[NSMutableDictionary alloc] init];
parameters = [NSDictionary dictionaryWithObjectsAndKeys:
height, @"user[height]",
weight, @"user[weight]",
nil];
[Client setParameterEncoding:AFJSONParameterEncoding];
[Client postPath:@"users/login.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"operation hasAcceptableStatusCode: %d", [operation.response statusCode]);
NSLog(@"response string: %@ ", operation.responseString);
NSDictionary *jsonResponseDict = [operation.responseString JSONValue];
if ([[jsonResponseDict objectForKey:@"responseBody"] isKindOfClass:[NSMutableDictionary class]]) {
NSMutableDictionary *responseBody = [jsonResponseDict objectForKey:@"responseBody"];
//get the response here
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"error: %@", operation.responseString);
NSLog(@"%d",operation.response.statusCode);
}];
これがうまくいくことを願っています。
AFNetworking 4 の場合
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
NSDictionary *params = @{@"user[height]": height,
@"user[weight]": weight};
[manager POST:@"https://example.com/myobject" parameters:params headers:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSLog(@"JSON: %@", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(@"Error: %@", error);
}];
AFNetworking 3.0（iOS9以上）の場合
NSString *strURL = @"https://exampleWeb.com/webserviceOBJ";
NSDictionary *dictParamiters = @{@"user[height]": height,@"user[weight]": weight};
NSString *aStrParams = [self getFormDataStringWithDictParams:dictParamiters];
NSData *aData = [aStrParams dataUsingEncoding:NSUTF8StringEncoding];
NSMutableURLRequest *aRequest = [[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:strURL]];
[aRequest setHTTPMethod:@"POST"];
[aRequest setHTTPBody:aData];
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:nil delegateQueue:nil];
[aRequest setHTTPBody:aData];
NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:aRequest completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
//
if (error ==nil) {
NSString *aStr = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"ResponseString:%@",aStr);
NSMutableDictionary *aMutDict = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
dispatch_async(dispatch_get_main_queue(), ^{
completionBlock(aMutDict);
NSLog(@"responce:%@",aMutDict)
});
}
else
{
dispatch_async(dispatch_get_main_queue(), ^{
NSLog(@"error:%@",error.locali)
});
}
}];
[postDataTask resume];
と追加
-(NSString *)getFormDataStringWithDictParams:(NSDictionary *)aDict
{
NSMutableString *aMutStr = [[NSMutableString alloc]initWithString:@""];
for (NSString *aKey in aDict.allKeys) {
[aMutStr appendFormat:@"%@=%@&",aKey,aDict[aKey]];
}
NSString *aStrParam;
if (aMutStr.length>2) {
aStrParam = [aMutStr substringWithRange:NSMakeRange(0, aMutStr.length-1)];
}
else
aStrParam = @"";
return aStrParam;
}
NSURL *URL = [NSURL URLWithString:@"url"];
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
NSDictionary *params = @{@"prefix":@"param",@"prefix":@"param",@"prefix":@"param"};
[manager POST:URL.absoluteString parameters:params progress:nil success:^(NSURLSessionTask *task, id responseObject) {
self.arrayFromPost = [responseObject objectForKey:@"data"];
// values in foreach loop
NSLog(@"POst send: %@",_arrayFromPost);
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(@"Error: %@", error);
}];
AFNetworking 3.0 および Swift 用。たぶん、次のように使用できます。
let configutation = NSURLSessionConfiguration.defaultSessionConfiguration()
manager = AFHTTPSessionManager(sessionConfiguration: configutation)
let urlString = "url"
manager.POST(urlString, parameters: [params here], progress: nil, success: { (dataTask: NSURLSessionDataTask, response: AnyObject?) -> Void in
print(dataTask)
print(response)
}) { (dataTask: NSURLSessionDataTask?, error: NSError) -> Void in
print(error)
}
これが私のような他の人が答えを見つけるのに役立つことを願っています!
NSMutableDictionary *dictParam = [NSMutableDictionary dictionary];
[dictParam setValue:@"VALUE_NAME" forKey:@"KEY_NAME"]; //set parameters like id, name, date, product_name etc
if ([[AppDelegate instance] checkInternetConnection]) {
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dictParam options:NSJSONWritingPrettyPrinted error:&error];
if (jsonData) {
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"Api Url"]
cachePolicy:NSURLRequestReloadIgnoringCacheData
timeoutInterval:30.0f];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:jsonData];
[request setValue:ACCESS_TOKEN forHTTPHeaderField:@"TOKEN"];
AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
op.responseSerializer = [AFJSONResponseSerializer serializer];
op.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/plain",@"text/html",@"application/json", nil];
[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
arrayList = [responseObject valueForKey:@"data"];
[_tblView reloadData];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
//show failure alert
}];
[op start];
}
} else {
[UIAlertView infoAlertWithMessage:NO_INTERNET_AVAIL andTitle:APP_NAME];
}
AFNetworking 3.0 を使用して、次のように記述します。
NSString *strURL = @"https://exampleWeb.com/webserviceOBJ";
NSURL * urlStr = [NSURL URLWithString:strURL];
NSDictionary *dictParameters = @{@"user[height]": height,@"user[weight]": weight};
AFHTTPSessionManager * manager = [AFHTTPSessionManager manager];
[manager POST:url.absoluteString parameters:dictParameters success:^(NSURLSessionTask *task, id responseObject) {
NSLog(@"PLIST: %@", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(@"Error: %@", error);
}];
